What is the minimum number of non-target fish associated with priority investigation criteria?

The minimum number of non-target fish associated with priority investigation criteria is defined as 500. This threshold is established based on the need for a scientifically robust sample size that can yield reliable data regarding non-target species. Such a large number ensures that the investigation adequately captures the diversity and population dynamics of these non-target fish, providing a comprehensive understanding of how various factors, such as environmental changes or management practices, may impact their populations. This level of sampling helps in minimizing sampling bias and enhances the overall validity of the results, making it easier to draw informed conclusions regarding the ecological health of the environment being studied.

A smaller number would likely not provide sufficient data to assess the variability and abundance of non-target fish populations accurately, which is crucial for effective environmental monitoring and management. The emphasis on gathering a robust sample size reflects the best practices in ecological research and monitoring, ensuring that findings can support sound decision-making.
